Methods and systems including leaf springs for a relay
An electromechanical relay is disclosed herein. The relay can include a first group of fixed and moving contacts arranged within a first assembly, a second group of fixed and moving contacts arranged within a second assembly, and a first magnetic device arranged between a first lateral wall and a second lateral wall of the first assembly and a second magnetic device arranged between first and second lateral walls of the second assembly, wherein the first and second magnetic devices include a first leaf spring and a second leaf spring, each of the first and second leaf springs including ends coupled to magnetic protrusions of the first and second magnetic devices, and wherein ends of the first and second leaf springs include a slot configured to receive one of the magnetic protrusions.
1 . An electromechanical relay, comprising: a first group of fixed and moving contacts arranged within a first assembly; a second group of fixed and moving contacts arranged within a second assembly; and a first magnetic device arranged between a first lateral wall and a second lateral wall of the first assembly and a second magnetic device arranged between first and second lateral walls of the second assembly, wherein the first and second magnetic devices comprise a first leaf spring and a second leaf spring, each of the first and second leaf springs comprising two ends coupled to magnetic protrusions of the first and second magnetic devices, and wherein each of the two ends of the first and second leaf springs comprise a slot configured to receive one of the magnetic protrusions.
2 . The electromechanical relay of claim 1 , wherein the first magnetic device is identical to the second magnetic device, and wherein the first and second magnetic devices are symmetric about two axes.
3 . The electromechanical relay of claim 1 , wherein the first leaf spring presses against the first lateral wall and the second leaf spring presses against the second lateral wall.
4 . The electromechanical relay of claim 1 , wherein the magnetic protrusions are welded to side surfaces of the first and second magnetic devices and extend toward the first and second lateral walls.
5 . The electromechanical relay of claim 1 , wherein a back surface of the first magnetic device faces a first longitudinal wall coupled to the first and second lateral wall of the first assembly, and wherein a back surface of the second magnetic device faces a first longitudinal wall coupled to the first and second lateral wall of the second assembly.
6 . The electromechanical relay of claim 1 , wherein a width of the first leaf spring of the first magnetic device is greater than a width of a gap between the first and second lateral walls in a relaxed state.
7 . The electromechanical relay of claim 1 , wherein the first magnetic device and the second magnetic device are identical.
8 . A system for an electromechanical relay, comprising:
a mounting plate comprising a plurality of magnetic assemblies, each of the magnetic assemblies comprising a plurality of moving contacts configured to actuate between corresponding fixed contacts, wherein lateral walls separate a first set of moving and fixed contacts from a second set of moving and fixed contacts, further comprising a magnetic device arranged in a gap between the lateral walls and retained within the gap via only leaf springs, wherein the leaf springs are positioned on a permanent magnet of the magnetic device via protrusions inserted into slots of the leaf springs, wherein the leaf springs create a threshold force that blocks removal of the magnetic device from the gap between the lateral walls in response to forces less than the threshold force.
9 . The system of claim 8 , wherein the leaf springs and protrusions are arranged on opposite sides of the permanent magnet.
10 . The system of claim 8 , wherein the mounting plate is symmetric about at least one axis.
11 . The system of claim 8 , wherein the gap in which the magnetic device is arranged is shaped via the lateral walls, a longitudinal wall, and a lip, wherein the lip is shorter than the lateral walls and longitudinal wall along a direction in which the magnetic device is inserted into the gap.
